Hmmm... Sounds like the drive might be failing... I don't like the 'error
4<abort>' bit... The 'Probable a portable PC' comment is thrown up after the
drive fails to signal with an interrupt... 
This is usually as the drive has spun down (ala laptop style), hence the
hopefully useful message...

By the look of the above I'd guess the drive is having a good try at reading
the data (causing the first warning) - then finally fails - giving the
second...

Check cabling etc. - but it really sounds like the drive is going bad :(
(wrtflt = writefault?)
